3.25 Choice of Position in Oblique Drawings
Orient the view so that important shapes are parallel to the viewing plane, as shown in Figure 3.62. In Figures 3.62a and c, the circles and circular arcs are shown in their true shapes and are easy to draw. In Figures 3.62b and d they are not shown in true shape and must be plotted as free curves or ellipses.
